＂三公＂调度现有评价指标仅关注年度发电计划执行的结果,而未考核执行的过程,可能造成发电企业收益不公平,从而影响＂三公＂调度的公正性和权威性。在分析＂三公＂调度现有评价指标存在问题的基础上,探讨了改进＂三公＂调度评价指标的工作思路,并尝试提出一种考虑煤价波动因素的＂三公＂调度评价新指标。该指标将发电企业之间的＂三公＂调度差异进行量化衡量,能够反映发电企业在收益上的公平性。算例分析表明,该指标计算简单、易于理解,有助于促进＂三公＂调度水平的进一步提高。
＂三公＂調度現有評價指標僅關註年度髮電計劃執行的結果,而未攷覈執行的過程,可能造成髮電企業收益不公平,從而影響＂三公＂調度的公正性和權威性。在分析＂三公＂調度現有評價指標存在問題的基礎上,探討瞭改進＂三公＂調度評價指標的工作思路,併嘗試提齣一種攷慮煤價波動因素的＂三公＂調度評價新指標。該指標將髮電企業之間的＂三公＂調度差異進行量化衡量,能夠反映髮電企業在收益上的公平性。算例分析錶明,該指標計算簡單、易于理解,有助于促進＂三公＂調度水平的進一步提高。

For the currently available evaluation indices of open,fair,and just power dispatching,attention is paid only to the final results of the annual power generation plan,to the neglect of the execution process.This may cause profit inequity among generation enterprises and affect the impartiality and authority of open,fair,and just power dispatching.Based on an analysis of the problem with the existing evaluation indices of open,fair,and just power dispatching,a new index considering the coal price fluctuation for evaluating the openness,fairness,and justness of power dispatching is proposed.The index quantifies the difference in open,fair,and just power dispatching between generation enterprises,which can reflect the profit equity of generation enterprises.The examples indicate that the index proposed can be simply calculated and easily understood,contributing to further improving the openness,fairness,and justness of power dispatching.
